Four dimensional lithospheric evolution and controls on mineral system distribution in Neoarchean to Paleoproterozoic terranes. This project will resolve important questions about the links between the evolution and preservation of continents and important mineral deposits in Australia and West Africa between 2.7 and 1.8 billion years ago. The results will improve the understanding of a key period of Earth history and make a major contribution to mineral exploration.
Resolving the influence of intraplate orogenesis on continental margin tectonics. Novel, multi-dating of continental sedimentary rocks will be undertaken to examine the effects of a high sediment flux from an enigmatic, major mountain-building event on a distant continental margin. This will expand our understanding of the range of tectonic influences between continental interiors and margins and onshore resource potential.
Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the ....Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the last 3.5 billion years. Preliminary research has validated the technique and demonstrated major changes in certain trace elements over geologically short periods. Outcomes will assist the minerals industry in the discovery of new deposits of zinc, copper, gold and iron ore in Australia.Read moreRead less
Earth's best-preserved Archean boninites: do they finally resolve the Archean mantle plume - plate tectonics controversy? Subduction typically starts on the modern Earth with the eruption of chemically distinctive rocks known as boninites. This project will study remarkably well preserved 2.85 billion year old boninites from Western Australia that may finally establish whether modern-style plate tectonics operated in the first half of Earth's history.

Events through time: eruptions, extinctions, impacts, ore-bodies and orogenies - upgrading the national argon geochronology network. Nine universities and the CSIRO will replace aged and obsolete equipment with new mass spectrometers which will be strategically placed at opposite ends of our continent to improve access for Australian researchers to these instruments for which there is high demand. These instruments will allow more exact dating of events such as eruptions, impacts, climate change ....Events through time: eruptions, extinctions, impacts, ore-bodies and orogenies - upgrading the national argon geochronology network.

Prospectivity of late Archean basaltic and gabbroic rocks associated with major gold and base-metal deposits. This project will establish a new set of criteria for the discovery of hidden deposits of gold, lead, zinc, copper and silver in rock aged between 2.8 and 2.6 billion years old. In 2009, the mining of these deposits contributed $5.5 billion dollars to Australia’s export earnings and provided the financial backbone for many regional communities.
Where to find giant porphyry and epithermal gold and copper deposits. This project will determine when and where giant gold or copper deposits should form, consolidating links with Indonesia, and using South East Asia as a vast natural laboratory in which to examine the effect of large-scale tectonic processes. The project will produce a four-dimensional virtual exploration toolkit to show how to apply the methods.

Summary
The role of hydrostatic pressure in modulating submarine silicic eruptions. Exploration on the modern seafloor reveals the deposits of deep (greater than 1 000 metres) silicic explosive eruptions, yet theory predicts that explosivity at these depths is largely suppressed. In 2012 the largest and deepest silicic submarine explosive eruption ever recorded took place at depths up to 1 600 metres, also challenging this theory. This project leverages a United States of America research expedition to ....The role of hydrostatic pressure in modulating submarine silicic eruptions. Exploration on the modern seafloor reveals the deposits of deep (greater than 1 000 metres) silicic explosive eruptions, yet theory predicts that explosivity at these depths is largely suppressed. In 2012 the largest and deepest silicic submarine explosive eruption ever recorded took place at depths up to 1 600 metres, also challenging this theory. This project leverages a United States of America research expedition to the eruption site. This project aims to constrain the physical and chemical factors that control explosivity using cutting-edge technologies. Australia's ancient submarine volcanoes host highly economic ore deposits. This project aims to enhance the ability to interpret ancient volcanic settings, thereby improving the potential for new ore deposit discoveries.Read moreRead less
